The murder weapon: Stromatolites - What are they?
Antonio de los Santos' contribution
Wikipedia: Stromatolites |
From Wikipedia, the free enciclopedia
"Stromatolites (from Ancient Greek στρῶμα (strôma), GEN στρώματος (strṓmatos) 'layer, stratum', and λίθος (líthos) 'rock') are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria and proteobacteria. These microorganisms produce adhesive compounds that cement sand and other rocky materials to form mineral "microbial mats". In turn, these mats build up layer by layer, growing gradually over time. A stromatolite may grow to a meter or more. Although they are rare today, fossilized stromatolites provide records of ancient life on Earth."
